SAFETY RAZOR Filed Nov. 1 4, 1936 Patented Apr. '26, 1 932 UNITED. STATES PATENT OFFICE- RALPH 'THOMPSON, OF BROOKLINE, MASSACHUSETTS, ASSIGNOR TO GILLETTE SAFETY RAZOR COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF DELA- WARE . SAFETY RAZOR Application filed November 14, 1930. Serial 110. 495,702.

This invention relates to safety razors, and

Fig. is a Sectional view taken on line -more particularly to means for so adjusting 5-5 of Fig. 3 and illustrating the form of i the razor and blade as to vary the blade edge exposure thereof. Some beards require a considerable exposure of the blade edge if a satisfactory shave is to be secured while other beards require a much less exposure. The

ideas of different people vary to a great extent in this matter and, furthermore, the same person ,may atone time desire a close shave and. at another time a rather rough shave.

. It is the primary object of my invention to produce a safety razor which may be readily satisfy these varying requirements.

Safety razors comprise a guard, a blade and such other parts as are necessary to hold theblade, in proper shaving position on the guard. In a safety razor of the Gillette type, these other parts include a cap for engaging the side of the blade opposite to that engaged by the guard, and means for clampin the cap and guard together with the blade erebetween, this means usually including the razor handle. In accordance with my invention, I so JIIOIIIlt and preferably pivot a stud I to the cap that movement thereof causes su'ch a relative transverse adjustment between the blade and guard as to. secure the said variations in blade exposure, the handle being adapted to cooperatewith the stud to clamp the parts in the adjusted positions. In the accompanying drawings I have illustrated certain specific embodiments of my invention but it, will be understood that the invention can be otherwise embodied and that the drawings are not to be construed as de- I fining or limiting the scope of the invention,

the claims appended hereto being relied upon for that purpose.

Referring to the figures of the drawings,

I have preferred to herein illustrate and describe my invention as applied to a safety razor of the Gillette type, it being understood,

however, that the same is by no means limited thereto. This type of "razor uses a double edged blade which is clamped into shaving position, between cap and guard members. My invention embodies means for adjusting the guard or blade transversely in such man- 14, two opposite edges of the blade being sharpened at 16 and 18. The blade is provided with three perforations along its center line,

the two outside perforations being adapted to -fit over two blade locating studs 20 on the cap and the intermediate perforation being adapted to fit over athreaded center stem or stud 22. This center stud is mounted for transverse pivotal movement on a pin 24 connected to the cap and for convenience I- have extended the stud through the cap and secured the pin to the outer face thereof.

TheQguard 14 is also provided with three stud receiving openings, two such openings 26 being adapted to receive the studs 20 and the central opening 28 being adapted to receive the pivoted stud 22.

' The stud 22 is mounted to have a limited pivotal movement in the cap 12 and this movement is adapted to provide the blade exposure adjustment above referred to. As illustrate diin Fig. 5, it Will 'be noted that two of the openings in the blade snugly fit the two studs 20 and prevent transverse movement of the blade on the cap, but that the corresponding openings 26 in the guard are wide enough to permit transverse adjustment of the guard. The intermediate opening in the blade, as shown in Fig. 4;, is wide enough to permit the full pivotal movement of the stud 22 and the corresponding opening 28 inthe guard closely fits about the stud 22. It will, therefore, be seen that transverse pivotal movement of the stud 22 will adjust the guard transversely relatively of the blade. As illustrated in Fig. 4:, the guard is adjusted to the right whereby the edge exposure at 16 has been increased and the edge exposure at 18 decreased. The razor handle 30 threadedly engages the stud 22 and tightening of the handle onto the arcuate abutments 32 on the guard clamps the parts firmly in their adjusted position.

It willbe clear that the edge exposure variation is produced by a relative transverse adjustment between the guard and blade and while I have above described the guard as being the adjustable member, the same result may be accomplished by adjusting the blade. I have shown such a modification in Figs. 6 and 7, wherein the cap 12', studs 20' and- 22 and handle 30 are substantially the same as in Figs. 1 to 5. In this construction, however, the blade holes whic ceive the studs 20 (Fig. 7 are sufliciently w deto permit a transverse adjustment of the blade and the corresponding guard holes 34 are of a size to closely fit the studs 20. The intermediate hole through the blade is also of a size to closely fit the stud 22 and the corresponding hole 36 in the guard is sufiiciently wide to permit transverse pivotal movement of this stud. It will, therefore, be seen that pivotal movement of the stud 22' will operate to adjust the blade transversely relatively to the guard. As illustrated in Fi 6, the blade is adjusted to the right where y the edge exposure at 18 has been increased and the edge exposure at 16' decreased. The tightening of the handle 30' is adapted to clamp the parts in the adjusted position.

vHaving thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A safety razor comprising a cap, a stud movably connected thereto, a guard loosely fitting the stud and cooperating with the cap to hold a blade therebetween, a blade perforated to fit the stud loosely, movement of the stud being adapted to cause a relative transverse adjustment between the guard and blade, and means engaging the stud for holding the parts in their adjusted position.

2. A safety razor comprisinga cap having a blade engaging face, a stud pivoted to adapted to hold a blade therebetween and swing transversely upon the cap and extending outwardly from said face, a guard having a blade engaging face and a hole for loosely receiving the stud, the said faces being 7 ll pivotal movement of the stud being adapted to act upon the blade to cause a relative transverse adjustment between the guard and blade, and clamping means engaging the stud for holding the parts in the adjusted position.

3. A safety razor comprising a cap having a blade engaging face, a stud pivoted to the cap for transverse movement and extending outwardly from said face, a guard having a blade engagin face and a hole for re ceiving the stud, a lade perforated to receive said stud loosely, the said faces of the caps and guard being adapted to hold the blade therebetween and pivotal movement of the stud being adapted to adjust the guard transverselyof the blade, and means engaging the stud for holding the parts in the adjusted position. v

4. A safetyrazor comprising a cap having 'a blade engaging face, a stud pivoted to the cap forv transverse movement and extending outwardly from said face, a guard having a blade engaging face and a hole for loosely receiving the stud, the said faces being adapted to hold a blade therebetween and pivotal movement of the stud being adapted to adjust the blade transversely of the guard, and means engaging the stud for holding the parts in the adjusted position.

5. A safety razor comprising a cap having a blade engaging face, a threaded stud pivoted to'the cap and extending outwardly from said face, a guard having a blade engagingface and a hole for receiving the 105 stud, the said faces being adapted to hold a blade therebetween and pivotal movement of the stud being adapted to cause a relative transierse adjustment between. the guard and blade, means providing an arcuate transversely extending abutment on the guard adjacent to'the said hole therein, and a handle threadedly engaging thestud and adapted to hold the parts in the adjusted positions b being tightened against said abutment.

6. Asafety razor comprising a cap having an inner concave blade-shaping surface, a threaded stem pivotally connected to the cap adjacent to its outer face and extending through the body of the cap, a flexible blade perforated to fit the stud closely, and guard apertured to' receive the stem loosely, whereby the blade may be transversely adjusted with respect to the guard by the pivotal movement thereof. 1 7.
